Abstract: 491,090. Immunizing crops against insects. POLLAK, J. E. (Ges. f³r Neuzeitliche Bodenbehandlung) Feb. 27, 1937, No. 5984. [Class 81 (i)] [Also in Group I] A method of immunizing crops, e.g. wheat, maize, cocoa beans and copra, against insects comprises thoroughly distributing silica in the form of finely divided sharp-edged or splinter-like particles throughout the crop in sacks by means of compressed air. If the treated crop contains a material quantity of silica, it is reduced to harmless amounts before human consumption. The silica also plays a useful part in the husking, decorticating, and polishing of cereal grains, and during polishing, is largely removed. A suitable apparatus consists of a container 4 for the silica into which air is blown by compressor 2, the dust being conveyed to a tube 7 formed with openings 8. The tube is introduced to the bottom of the sack 9, valve 11 is opened, and the tube slowly withdrawn. In a modified apparatus, the compressed air conduit is connected to a valved injector device for the silica disposed at the top of the dip tube. The top of the tube may also be provided with a valve controlling the compressed air conduit.

Patent GB-679914-A (GB)
Title: Improvements in method of reclaiming the hydrocarbon content of used hydrocarbon lubricants
IPC: C10M175/00
Filed: 1949-03-08
Abstract: Hydrocarbon lubricants are treated to recover the hydrocarbon compounds therein by agitating the lubricants with an aqueous solution containing ethylene diamine tetra-acetic acid and an alkali metal hydroxide, in amounts such that 2-4 molar weights of the alkali metal hydroxide are provided for each molar weight of the acid, and then separating the hydrocarbons from the aqueous solution.  In one example, to 1 litre of used automobile oil is added 100 cc. of a 30 per cent solution of caustic soda and ethylene diamine tetra-acetic acid containing 2-3 molar weights of the hydroxide to each molar weight of the acid.  The mixture is heated and when cool the two layers are separated.  The bottom layer, containing sodium soaps, poly-metallic salts, complex compounds of the di-sodium salt of the tetra acid and suspended carbon particles, is filtered and the filtrate acidified to a pH of 4.5; the fatty acids are then separated from the water fraction, which is acidified to the isoelectric point of the tetra-amino acid.  The upper hydrocarbon layer from the first separation is neutralized with caustic alikali, the soaps formed separated from the hydrocarbon compounds and acidified to obtain the fatty acids.  In another example, automobile oil is treated with the di-sodium salt of ethylene diamine tetraacetic acid but in this case the fatty acids are completely isolated in the hydrocarbon layer.

Title: Improvements in agricultural and like balers
Inventor: BAMFORD HENRY VINCENT
IPC: A01F15/14
Filed: 1956-03-02
Abstract: 810,775. Baling-machines. BAMFORDS Ltd. March 1, 1957 [March 2, 1956], No. 6534/56. Class 94(1). In a baling machine e.g. of the " pick-up ' type described in Specification 755,857, the ty ing mechanism 11 it driven through a spring clutch 12 controlled by a metering wheel 18 which is rotated by movement of a bale in formatior through the baling chamber 10. The clutch is normally held out of engagement by a trip lever 14 engaging a nose 13, the lever being pivoted at 15 and urged by a spring 17 to the position shown in Fig. 2. Pins 26 on either side of the lever engage slots 25 in a fork 23 connected to a trip rod 22 which is formed with a rack 21 engaging a pinion 20 on the shaft of the wheel 18, the effective length of the slots being adjustable by a screw 29 which varies the position of a slidable roller arranged to engage the edge of the lever 14. The rack 21 is normally maintained in operative engagement with the pinion 20 by a roller 33 on an arm 34 which is pivoted at 35 to a fixed bracket 35a and urged downwardly by a spring 36. The arm 34 has a lost-motion connection 37 with one end of a link 38, the other end of which is coupled to an arm 40 which is swung to the left during the tying operation. As the wheel 18 rotates, the rod 22 is moved to the left until the ends 27 of the slots 25 engage the pins 26 and swing the lever 14 clear of the nose 13, thus allowing engagement of the clutch 12 to operate the tying mechanism. The rack 21 terminates in a recessed portion 31 so that its teeth are automatically disengaged from the pinion after a predetermined movement to prevent further rotation of the wheel 18 being transmitted to the rod 22. At the same time, a slot 43 on the rack engages the roller 33 so that when the link 38 is moved to the left during the tying operation, the resultant upward pivotal movement of the arm 34 raises the rack clear of the pinion so that it is free to return to its initial position under the action of a spring 44. The arm 34 is coupled by a chain 47 to a counter 48 which records the number of bales formed by the machine.

Title: A fluid pressure sensing mechanism operatively arranged to compensate for changing environmental conditions
IPC: B64D45/00
Filed: 1962-02-21
Abstract: 953, 616. Pressure sensitive devices. BENDIX CORPORATION. Feb. 21,1962 [Feb. 27, 1961], No. 6786/62. Headings G1L and G1N. Temperature-compensated pressure responsive apparatus comprises a rocking-shaft 18 linked via bi-metallic linkages 82, 83 to a pair of symmetrically positioned co-operating pressure sensitive capsules which are themselves supported on temperature-responsive mountings including bimetallic posts 107, 108 which flex with temperature variation and bear against (or allow withdrawing movement of) leaf springs 96 carrying the capsules to adjust the position of the latter so as to cancel rotation of the shaft due to temperatureinduced capsule expansion (contraction). Rotation of shaft 18 is transmitted via a differential gear assembly 26 to a rotor core 28 of a differential transformer 30, the signal being amplified and applied to a two-phase servomotor 191 to drive shaft 199 and, via the ring gear 203 on the gear casing 136, produce epicyclic rotation of the output gear 162 to restore the rotor core 28 to a null position. For very large pressure changes, excessive rotation of shaft 18 causes the arm 240 to close either switches 235-236 or 237-238 to give an input signal on the amplifier which causes overriding opposite rotation of motor 191, and hence shaft 199, to prevent movement of the rotor core 28 beyond its normal operating range. At the same time gear 234 is rotated to open the switch that has been closed. An anti-hunting motor G is linked to the main servomotor 191.

Abstract: 694,677. Cooling-systems for engines. DAIMLERBENZ-AKT.-GES. March 27, 1951 [March 25, 1950], No. 7125/51. Class 64(iii) [Also in Groups XXVII and XXXIV] The coolant of the main engine 1 normally flows through pipe 6, and radiator 7, and returns to the engine by pipe 8 and coolant pump 9 whilst a valve 13, in the position shown, connects the cooling-jacket of the main engine 1 to a pipe 11 leading to the cooling jacket of the auxiliary engine 4 and closes the pipe 6. In its other position the valve 13 establishes the normal circuit for the main engine coolant and either closes pipe 11 or connects it to the auxiliary-engine coolant-outflow conduit 10 by a pipe 14; the pipe 11 either leads to the auxiliary-engine cooling-jacket or a coolant pump 12 driven thereby, whilst the pipe-10 opens into the pump 9 or the main engine cooling- system. After the auxiliary engine has been started (see also Group XXVII) its heated coolant is directed by valve 13 through the cooling-jacket of the main engine 1 until the latter attains a temperature sufficient to actuate a thermostat 21 and so couple together the auxiliary and main engines for starting purposes. The valve 13 is actuated by a hand lever 27, used to stop the auxiliary engine, to restore the normal coolant circuit of the main engine. In a modification, the heated cooling-water from the auxiliary engine passes through a heat exchanger in a line which joins the flow and return pipes of the cooling-system of the main engine, the opening and closing of the line being under the control of a thermostat.
